Having a crowdfunding by a gambling site is not a good idea, its better to have a private investorss than making a crowdfund.
What kind of share you will give for a tester?
Even though investment is a game of probability, there is need for a very great and irresistible value proposition from a given project.
You know gambling is the highest of a risky business, combining it with crowd funding is not very suitable for investors unless the gain is very very great.
If investors are gamblers who hide their money from their passion for gambling, then the value proposition of our project is completely irresistible for them. Saving money that would otherwise be lost at the casino!
